I have a Roku TV, and I want to get Roku to get the movies. I have no idea how to go about getting it. I have been searching the Internet, but I'm old (70) can any body out there help me? When I go to the Roku it says that I need a number and a pass word. I know what those are but how do I get them? then how do I connect to Roku? I'm sorry but I just don't get it.﻿
